Several factors have contributed to this debate, including the lack of a clear distinction between intergenerational and transgenerational epigenetic inheritance (TEI), the inconsistency of some studies, the potential confounding effects of in-utero vs. epigenetic factors, and, most importantly, the biological challenge of epigenetic reprogramming. Two waves of epigenetic reprogramming occur: in the primordial germ cells and the developing embryo after fertilization, characterized by global erasure of DNA methylation and remodelling of histone modifications. Consequently, TEI can only occur if specific genetic regions evade this reprogramming and persist through embryonic development. These challenges have revived the long-standing debate about the possibility of inheriting acquired traits, which has been strongly contested since the Lamarckian and Darwinian eras. As a result, coupled with the absence of universally accepted criteria for transgenerational epigenetic studies, a vast body of literature has emerged claiming evidence of TEI. Therefore, the goal of this study is to advocate for establishing fundamental criteria that must be met for a study to qualify as evidence of TEI. We identified five criteria based on the consensus of studies that critically evaluated TEI. To assess whether published original research papers adhere to these criteria, we examined 80 studies that either claimed or were cited as supporting TEI. The findings of this analysis underscore the widespread confusion in this field and highlight the urgent need for a unified scientific consensus on TEI requirements.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":"19 1","pages":"2333586"},"PeriodicalIF":3.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10965103/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140206498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, infrequent-feeding species who commonly experience food shortages might evolve more adaptive strategies to cope with food deprivation than frequent-feeding species. Thus, the present study aimed to test whether the response of hypoxia tolerance in fish to short-term fasting (2 weeks) varied with different foraging modes. Fasting resulted in similar decreases in maintenance energetic expenditure and similar decreases in P<sub>crit</sub> and P<sub>loe</sub> between fishes with different foraging modes, whereas it resulted in decreased oxygen supply capacity only in frequent-feeding fishes. Furthermore, independent of foraging mode, fasting decreased P<sub>crit</sub> and P<sub>loe</sub> in all Cypriniformes and Siluriformes species but not in Perciformes species. The mechanism for decreased P<sub>crit</sub> and P<sub>loe</sub> in Cypriniformes and Siluriformes species is at least partially due to the downregulated metabolic demand and/or the maintenance of a high oxygen supply capacity while fasting.

Hence, in this study, we sought to investigate the dose-response effect of GSK-3α/β inhibition in the pathogenesis of obesity-induced T2D. Specifically, to gain insight into the dose-response effect of GSK-3 isoforms in T2D, we generated tamoxifen-inducible global GSK-3α/β heterozygous mice. GSK-3α/β heterozygous and control mice were fed a high-fat diet (HFD) for 16 wk. At baseline, the body weight and glucose tolerance of GSK-3α heterozygous and controls were comparable. In contrast, at baseline, a modest but significantly higher body weight (higher lean mass) was seen in GSK-3β heterozygous compared with controls. Post-HFD, GSK-3α heterozygous and controls displayed a comparable phenotype. However, GSK-3β heterozygous were significantly protected against obesity-induced glucose intolerance. Interestingly, the improved glucose tolerance in GSK-3β heterozygous animals was dampened with chronic HFD-feeding, likely due to significantly higher fat mass and lower lean mass in the GSK-3β animals.

The treatment of LC patients is facing great challenges. Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is a LC marker that has been discovered in recent years, and there are sporadic data suggesting that it has an impact on the level of chemoresistance, but the exact mechanism remains to be deciphered. Our investigation, grounded in bioinformatics strategies including the TCGA database, GEO database, K-M plot database, GSEA, Pearson correlation analysis, and detection of clinical samples, led to the identification of TPX2 and its upstream transcription factor E2F8 as differentially expressed elements in LC tissues. We also probed the role of the axis in glycolysis, angiogenesis, tumor progression, and chemoresistance in LC cells. This was achieved by a battery of molecular and cellular experiments, such as qRT-PCR, CCK-8, Transwell, flow cytometry, and angiogenesis assays. Both TPX2 and E2F8 were upregulated in LC tissues and cells with E2F8 being responsible for the upregulation of TPX2. Through bioinformatics analysis, we observed a significant enrichment of TPX2 in the glycolysis and angiogenesis pathways. Cell-based experiments corroborated these findings, demonstrating that TPX2 knockdown led to significant inhibition of glycolysis and angiogenesis, along with a suppression of the malignant progression of LC cells. This was mirrored by a reduction in the IC<sub>50</sub> values for cisplatin and apatinib to 0.8257 µM and 10.79 µM, respectively. In contrast, E2F8 overexpression reversed these effects in LC cells, increasing the IC<sub>50</sub> values to 3.375 and 16.06 µM, respectively. The E2F8-TPX2 axis promotes glycolysis and angiogenesis in LC cells, which in turn accelerates cancer progression and reduces chemosensitivity.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-024-00655-w.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":"76 6","pages":"817-832"},"PeriodicalIF":2.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11490592/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142460027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
